Abstract

An aerosol delivery device comprises: a flow passage configured to provide fluid communication between a vaporizer and a mouthpiece aperture, so that the mouthpiece aperture receives a flow comprising an aerosol vapor formed from liquid vaporized by the vaporizer in use; and a turbulence inducing element, the turbulence inducing element located in the flow passage and configured to turn the flow towards a circumferential direction of the aerosol delivery device.

Claims (27)

1 . An aerosol delivery device comprising:

a flow passage configured to provide fluid communication between a vaporizer and a mouthpiece aperture, so that the mouthpiece aperture receives a flow comprising an aerosol vapor formed from liquid vaporized by the vaporizer in use; and

a turbulence inducing element, the turbulence inducing element located in the flow passage and configured to turn the flow towards a circumferential direction of the aerosol delivery device.

2 . An aerosol delivery device according to claim 1 further comprising the vaporizer.

3 . An aerosol delivery device according to claim 2 , wherein the aerosol delivery device comprises a vaporizer chamber containing the vaporizer, and wherein the turbulence inducing element is at least partially located in the vaporizer chamber.

4 . An aerosol delivery device according to claim 1 , wherein the turbulence inducing element is located at least 1 mm downstream of the vaporizer.

5 . An aerosol delivery device comprising:

a vaporizer configured to form an aerosol vapor from e-liquid;

a flow passage configured to provide fluid communication between the vaporizer and a mouthpiece aperture, so that the mouthpiece aperture receives a flow comprising the aerosol vapor in use;

a turbulence inducing element, the turbulence inducing element located in the flow passage and configured to induce turbulence in the flow; and

a vaporizer chamber containing the vaporizer and the turbulence inducing element, wherein the turbulence inducing element is at least 1 mm downstream of the vaporizer.

6 . An aerosol delivery device according to claim 5 , wherein the turbulence inducing element is at least partially located within the vaporizer chamber.

7 . An aerosol delivery device according to claim 4 , wherein the turbulence inducing element is at least 2 mm downstream of the vaporizer.

8 . An aerosol delivery device according to claim 7 , wherein the turbulence inducing element is at least 2.5 mm downstream of the vaporizer.

9 . An aerosol delivery device according to claim 4 , wherein the turbulence inducing element is at most 5 mm downstream of the vaporizer.

10 . An aerosol delivery device according to claim 9 , wherein the turbulence inducing element is at most 4 mm downstream of the vaporizer.

11 . An aerosol delivery device according to claim 4 , wherein the turbulence inducing element is substantially 3 mm downstream of the vaporizer.

12 . An aerosol delivery device according to claim 5 , wherein the turbulence inducing element is configured to turn the flow towards a circumferential direction.

13 . An aerosol delivery device according to claim 5 , wherein the turbulence inducing element is further configured to turn the flow towards a radial direction of the aerosol delivery device.

14 . An aerosol delivery device according to claim 13 , wherein the turbulence inducing element comprises a baffle across the flow passage, the baffle forming a first flow obstacle to turn the flow towards the radial direction.

15 . An aerosol delivery device according to claim 14 , wherein the baffle is configured to effect branching of the flow.

16 . An aerosol delivery device according to claim 5 , wherein the turbulence inducing element comprises an upstand, and the flow passage comprises an outlet tube, wherein the outlet tube and the upstand are configured to together form a second flow obstacle to turn the flow towards the circumferential direction.

17 . An aerosol delivery device according to claim 16 , wherein the second flow obstacle is configured to effect additional branching of the flow.

18 . An aerosol delivery device according to claim 5 , wherein the turbulence inducing element comprises an outlet, the turbulence inducing element further configured to turn the flow such that the flow is in a substantially axial direction at the outlet.

19 . An aerosol delivery device according to claim 18 , wherein the turbulence inducing element comprises a protrusion forming a third flow obstacle to turn the flow towards the axial direction.

20 . An aerosol delivery device according claim 5 , further comprising a reservoir for storing a liquid, the reservoir in fluid communication with the vaporizer to pass liquid to the vaporizer for vaporization.
